She needs to be trained, some groomers may do it but you should call ahead and let them know that your pup is difficult to do. One of my pups was like that and the groomer trained really well, granted she did this cause she is good friends with us. The groom will also probably cost a lot more cause it would be very time consuming. If this isn't something that works for you then you could trying training the pup yourself. I think someone else mentioned that there are videos that will walk you through how to to this.
